I am currently running three raspberry pi 3's in a library as digital signage, two wireless and one wired. They reboot every 12 hours, sync to a windows share, grab new images, and then runs a looping eom slideshow. The issue I'm having is that the Pi's would regularly boot in a tty login screen which prevents the Pi from reaching the desktop and starting signage process.
I followed the instructions in this link which seems to have decrease the frequency of the attempts, however the login attempts still continue.
I was hoping someone could help me with this.
